We developed SpikeHunter, a new method using AI to identify phage tailspike proteins, crucial for determining bacterial host specificity. This tool helps discover new phage therapies by linking proteins to bacterial serotypes.
Area of Science:
- Microbiology
- Bioinformatics
- Structural Biology
Background:
- Phage tailspike proteins are key determinants of phage host specificity, targeting bacterial surface glycans.
- Identifying these proteins is challenging due to their high sequence diversity.
Conclusions:
- SpikeHunter effectively identifies phage tailspike proteins and their serotype associations.
- Tailspike protein domains, especially the C-terminal, play a significant role in determining phage host range.
- The findings offer valuable insights for advancing phage therapy and biotechnology applications.
